Statistical Analysis: Summarizing Evidence Versus Establishing Facts
(American Psychological Association, 1985)
We contrast our view of the primary role of statistical analysis as an aid to summarizing evidence with the view that its primary role is to establish facts. Some implications of these differing viewpoints for the publication ...
Meta-Analytic Procedures for Combining Studies With Multiple Effect Sizes
(American Psychological Association, 1986)
In this article we present a general set of meta-analytic procedures for combining and comparing research results from studies yielding multiple effect sizes based on multiple dependent variables. These require, in addition ...
Comment: Assumptions and Procedures in the File Drawer Problem
(Institute of Mathematical Statistics, 1988)
Effect Size Estimation for One-Sample Multiple-Choice-Type Data: Design, Analysis, and Meta-Analysis
(American Psychological Association, 1989)
This article proposes a standard, easy-to-interpret effect size estimate for one-sample research. The proportion index (*•) shows the hit rate on a scale on which .50 is always the null value regardless of the number of ...
Comparing Effect Sizes of Independent Studies
(American Psychological Association, 1982)
This article presents a general set of procedures for comparing the effect sizes of two or more independent studies. The procedures include a method for calculating the approximate significance level for the heterogeneity ...
Further Meta-Analytic Procedures for Assessing Cognitive Gender Differences
(American Psychological Association, 1982)
We describe procedures for (a) assessing the heterogeneity of a set of effect sixes derived from a meta-analysis, (b) testing for trends by means of contrasts among the effect sizes obtained, and (c) evaluating the practical ...
Ensemble-Adjusted p Values
(American Psychological Association, 1983)
When contrasts or other tests of significance can be ordered according to their importance, adjusted p values can be computed that permit greater power to be brought to bear on contrasts of greater interest or importance. ...
Multiple Contrasts and Ordered Bonferroni Procedures
(American Psychological Association, 1984)
This article presents a general yet simple system for avoiding the increases in Type I errors that typically occur when an increasing number of contrasts is to be computed. The procedures described are all based on the ...
Comparing Within- and Between-Subjects Studies
(Sage, 1980)
Studies employing within-subjects designs may be compared with those employing between-subjects designs in a variety of ways. We discuss and illustrate the comparisons of variabilities, including within-condition variances ...
A Simple, General Purpose Display of Magnitude of Experimental Effect
(1982)
We introduce the binomial effect size display (BESD), which is useful because it is (a) easily understood by researchers, students, and lay persons; (b) widely applicable; and (c) conveniently computed. The BESD displays ...
